" AIATo aZZwhomz'tv/Lay'coneemf L Be i known .that I,.Q'rro A. WALs'rAD, a f citizen of the United States, resident of- Mm- Ane`a1: olis,`county of Hennepin, and State of l Minnesota,` have invented certain new and useful Improvements in'A Detachable. Win,- dows, of which the ,following is a specificationm. .M l The object of my invention is to provide a l. window inthe construction and'useof which sash pockets and window weights. are en.4 tirely eliminated, thereby permitting theinsertion of afwindow into a-'smaller space andallowing windows to be. arranged nearerjto-- l5- getler than where the usual sash. weightpocketsarenecessary@ A further object, is. to provide. a.- window ihaving sash whichcan be easily and quickly detached from the frame and reversed if. 20 desired for cleaning or other' purposes;

:A flirt-her object' is to provide a. window. mounted in such a way'irfthe sash that wind .and dust-cannot work into the room around the window and the use 'of the ordinary 85 weather stripis renderedinnecessary.;

. yAi further object is to Drovidev a window in whicl-i one or Vboth sash may be`made `removable-and'- either sash, when so constructed., can be adjusted at any point in its frame and I0 held in Asuch adjustment without the use of .'vveights or spring catches. Other objects of the invention will appear from the following detailed description.

`. The invention consists generally in various 86' 'constructions and combinations, all as hereinafter described and particularly' pointed out inthe claims. A In. .theaccompanying drawings forming part of this specification, 40 Figure' 1 isa front. elevation of embodying my invention, y

Blocks l'of'suitable' material, preferably wood, are" fitted into :the recess 7 and have rabbets 11l in their outer edges wherein the light of glass 12 isseated, the rabbet being of suiicient depth yso that the outer surface lof the glass is flush substantially with the surface of the block. 'I fheblocks are seated against the middle portion of 1 the rails; joining the -inner and louterflanges, as shown in Figure4, and the'blo'cks are of substantial width, so that they ex- 4tend approximately to the rear `tvall of the recess and efectually close the joint around` l the glass to the entrance of air' or moistureysl. .I

.Spring lplates 13, preferably 'of nictal arev inter rosed between the facev of the glass the anges 9, as shown in Figure 4, one longitudinal edge of the plateresting on the'.4N

block 1 0 and the other corresponding edge! being seated on the surfaceof the glass, hold- 85 ing it snugly on its seat with a yielding .presc y sure. The side rails 3 of the window frame e are provided preferably with metallic face g plates 15 which extend from the lower rail 41 to the upper rail- 2. Spring guide plates 16 90 are mounted upon-the face plates 1'5 and secured to the side rails 3 by suitable means such as nails 17, as shown in Figure 3, the spring guide plate normally bearing at one sidelupon the faceplates l5 butpapable of being separated therefrom. These guicile plates .extend from the ends of the windowframe side ,rails on both sides-to points nearv the middle portion'thereof, as indicated in Figure 1, and the inner ends 18 of thesef'loo plates are preferably turned outwardly, as indica-ted to form gui-des for the flanges 9 of 'the window sash, see Figure 3,'swhere the flange 9 is shown inserted betweentheface plate 15 and the guide plate 16-and held by 105 f.

frictional engagement with Vsaid plates in miy i any position in the opening or closing of the sash. The side and end rails of the sash are made in substantially the same mannen-S- shaped in cross section, the only difference being that the side rails are longerthan those at the top and bottom. This construction permits convenient assembling, any two rails serving for the side rails ofthe sash andthe top and. bottom lrails may be easily icked and fitted in place without any ad- ]ustment or locking for specially fnadepart's.

Both sides of the window at the top and bottom are equipped with these guide plates 16,/ with a gap between the adjacent ends near the middle ofthe window, as shown plainly in Figure 1', so that the upper end 4ofthe' lower sash, when it is its closedv position, will be out ofengagement with the upper ides and if it is desired to remove the sas it is only necessary. to lraise the lower sash until its lower portion is out of engagementwith the lower guide lates 16, AVthen pull its lower portion' slig tly outward, as shownin F1gure`2,.and lower it outside of the lower guide plates ^16 until it is released from. the upper guide-plates.

-- lThe sash maythen be removed lfrom the window.l The same/operation applies to the upper sash, only the movement willbe reve ed .For the Qrpose. of holding the guide strips or p ates with a vyielding -pressure aglnstthe sash, I prefer to provide ^the .side rails of the frame 'with clamping strips or bars 19 having inwardly turned ortions 2O adapted-to bear on the guide p ates 16 for holding them with an increasing or de- "creasing pressure, as preferred, against the mjflanges 9 so that suiiicient friction will be produced"A for holding the sash vertically in any ad'usted position, (Fig. 3). The pres-1 `surey o these clamping 'bars .on theguide plates may be increased or decreased by suitable means, such as screws 21,' which pass through the bars into the side railsof the frame. Tightening these-screws will increase the "pressure of the guide plates on the sash and looseningthescrews will relieve such pressure. Evidently, as indicated in Figure 5, with the lian e 9a sliding under y the guide plates, there wi l be no possibility of air or dust entering the house around the railsof thesash, a dust and air tight joint being formed vat this; eine At the Sametime, whenever desire thesaslican bei easily and quickl detached from the.

- yguides as above descri ed.- The guides may be made of any suitable material, but

prefrably of alight, thin gauge of metal which will yieldv and adapt vitselfto the positions of the sash and at the same time will hug the flanlges thereof and hold the sash in any position inwhich it may be -ad'usted ln Figures 1 and 2, there is shown a window frame having only -thee-lower 4sash j adjustably' and removably ymunted therein,

y is adapted to enter therecessS in t e bottom rails when the lower sashis closedas indicated in Figure 5, thus forming air and dust;`

rtight joints at this point.

. Means are alsoprovlded for thepurpose of providing an. air and dust-tight'j'oint 1 between the u perJ portion of the sash and Y the'center ra1l 23\of the window frame, when'the sash isin its down'orclosed position. A rece 26 is preferably provided `in* the low r portion of the cens ter rail 23 Vadjacent the sash, adapted rto.

ping consisting of a strip of suitable fa ric, which secured toi. the center rail by suitable means-such as -a bar 28. Against thisllexibie weather str/ippingthe flange 9"- is seated when the sashis in .its closed po# Isition, as indicatedin Figure 4.' j A Y A-In Figure 6, Ihave shawn a modied construction in which vboth the`1 1ppe 1 and lowersash of the\' window are dl-ustably l and removably, m ntedjin the frame. In this figure it will e noted'that "thedetails of construction of each sash" and. also the supporting means therefor, are'substantially identical to the vdetails of I constifJuctionV ;of` the removable 'sash and supporting means, shown in Figure 2, ,andit is therefore Iunnecessary to. .describesafm'e 'in y tail, `like parts being represented ,'by." 1l ik f'referen'ce' .numerals ThevlowersashinfFi" "re 6 isA i shownjn` its downorc losedf,-A osition, itsoperation, however, fbe1n g sinn anillo that y*of thelower sash, TshownuinV Figure 2.
